Use pretty-simple to format native output. Previously we used our own homespun formatting. But this produces over-long lines that aren't ideal for diffs in tests. Easier to use something off-the-shelf and standard. Closes #7580. Performance is slower by about a factor of 10, but this isn't really a problem because native isn't suitable as a serialization format. (For serialization you should use json, because the reader is so much faster than native.) 2021-09-19 21:09:51 +02:00			`[ Plain`
Switch from pretty-simple to pretty-show for native output. Update tests. Reason: it turns out that the native output generated by pretty-simple isn't always readable by the native reader. According to https://github.com/cdepillabout/pretty-simple/issues/99 it is not a design goal of the library that the rendered values be readable using 'read'. This makes it unsuitable for our purposes. pretty-show is a bit slower and it uses 4-space indents (non-configurable), but it doesn't have this serious drawback. 2021-09-29 06:17:53 +02:00			`[ Span`
